BACKGROUND: Recently, some new methods for sexing of chicken eggs by fluorescence and Raman spectroscopy through the shell membrane have been proposed. On the other hand, in another investigation, a new virus medical imaging has been suggested. AIM: In this research, summing over these considerations, a new technique for sexing of chicken eggs by virus spectroscopy through the shell membrane is proposed. METHODS: (Please, add text …) RESULTS: (Please, add text …) CONCLUSION: It is shown that viruses outside the shell of egg can communicate with materials inside it and determine the gender of chick embryo and its evolutions.

To recover chick embryos damaged the brain, two methods are presented. In both of them, somatic cells of an embryo introduced into an egg cell and an embryo have emerged. In one method, injured a part of the brain in the head of an embryo is replaced with a healthy part of the brain. In the second method, the heart of brain embryo dead is transplanted with the embryo heart. In this mechanism, new blood cells are emerged in the bone marrow and transmit information of transplantation to subventricular zone (SVZ) of the brain through the circulatory system. Then, SVZ produces new neural stem cells by a subsequent dividing into neurons. These neurons produce new neural circuits within the brain and recover the injured brain. To examine the model, two hearts of two embryos are connected, and their effects on neural circuits are observed.

Recently, some scientists from NASA have claimed that there may be a black hole like structure at the centre of the earth. We show that the existence of life on the earth may be a reason that this black hole like object is a black brane that has been formed from biological materials like DNA. Size of this DNA black brane is 109 times longer than the size of the earth's core and compacted interior it. By compacting this long object, a curved space-time emerges, and some properties of black holes emerge. This structure is the main cause of the emergence of the large temperature of the core, magnetic field around the earth and gravitational field for moving around the sun. Also, this structure produces some waves which act like topoisomerase in biology and read the information on DNAs. However, on the four-dimensional manifold, DNAs are contracted at least four times around various axis's and waves of earth couldn't read their information. While, by adding extra dimensions on 4 +n-dimensional manifold, the separation distance between particles increases and all of the information could be recovered by waves. For this reason, each DNA has two parts which one can be seen on the four-dimensional universe, and another one has existed in extra dimensions, and only it's e_ects is observed. This dark part of DNA called as a dark DNA in an extra dimension. These dark DNAs not only exchange information with DNAs but also are connected with some of the molecules of water and helps them to store information and have memory. Thus, the earth is the biggest system of telecommunication which connects DNAs, dark DNAs and molecules of water.

AIM: In this paper, inspiring Darwin’s theory, we propose a model which connects evolutions of neural circuits with evolutions of cosmos. In this model, in the beginning, there are some closed strings which decay into two groups of open strings. METHODS: First group couple to our universe from one side and produce matters like some genes of DNAs and couple to an anti-universe from another side with opposite sign and create anti-matters like some anti-genes of anti-DNAs. Second group couple to the star and planet’s cores like the earth’s core from one side and produce anti-matters like stringy black anti-DNA and couple to outer layers of stars and planets like the earth from other side and produce matters like some genes of DNAs on the earth. Each DNA or anti-DNA contains some genetic circuits which act like the circuits of receiver or sender of radio waves. To transfer waves of these circuits, some neurons emerge which some of them are related to genetic circuits of anti-DNAs in anti-universe, and some are related to genetic circuits of stringy black anti-DNA within the earth’s core. A collection of these neural circuits forms the little brain on the heart at first and main brain after some time. RESULTS: To examine the model, we remove effects of matters in outer layers of earth in the conditions of microgravity and consider radiated signals of neural circuits in a chick embryo. We observe that in microgravity, more signals are emitted by neural circuits respect to normal conditions. This is a signature of exchanged waves between neural circuits and structures within the earth’s core. CONCLUSION: These communications help some animals to predict the time and place of an earthquake.

BACKGROUND: Cutaneous angiosarcoma of the head and neck region is a subtype of cutaneous angiosarcoma with an unfavourable prognosis. Diagnosis is often delayed.

Topical treatment is the cornerstone for the management of mild to moderate psoriasis. Despite efforts in drug development, patient's satisfaction with the available topical treatments is limited. A strategy to improve safety, efficacy and comfort of topical treatment provides the development of new drug delivery and drug carrier systems. This review provides an overview of recent advances in this field with a focus on psoriasis. Laser-assisted drug delivery, foam formulations, nanoparticles, ethosomes, and niomes are considered. Hopefully, these new developments will improve topical drug therapy and patient satisfaction.

The Bulgarian Society for Dermato-Surgery (BULSDS) has been founded by Prof. Dr. Georgi Tchernev in 2018. The aims of the society are to support and develop dermato-surgery as an integral part of dermatology in Bulgaria, to improve interdisciplinary cooperation and to evolve special proposals for education and training. The society works together with international partners. The 1st Congress of BULSDS was held from March 15 to 16 2019 in the Bulgarian capital Sofia. The main topic of this congress with international participation was dermato-oncology
